' Atpiiatin mdf-iraien- 18, 192e:r sensi m'. 95,1524.' l l My invention. reist-s to, enveiapgs, and particularly to envelopes forjmailing pu-1v poses 4whichthe Post .OHice-regulations re#i quire. tolbe sealedjv'vithl wax in order to pre-y 5 vent tamperingwithl the same' dnrin'gtheir` transmis'sion.;`

Envelopes., of f the ktype contemplated by my `invention are" used. 'for mailing", securities,

Oiice will register andinsurethe same, itis required that all the .parts ,comprising the envelope be sealed together by wax, and-1n the, commorrformof. envelopeused atthe'l present time, three sealsj-arerequiredto securenll the adjoining,A and abutting edges. Considerablatime ,is kconsumed ,in placin'g thesealing. wax upon these different points of contactzo'nr the present form of envelope', and 4,theweight of, the seals constitutes quite a actorin ythe mailingexpense.

The Aobject of my invention is to" provide a..cheap. and simple form of rnaili'ngen-` velope wherein all theoverlapping,abutting edgesfare fconcentrated 'lat one point and :aty

thislpoint asingle` application of sealing` wax will` sealfall the parts-together, so that the. cannot bedisconnected without fracturing. or .otherwise distorting, the sealing wax, so thatany tampering with the envelope..wl1.be apparent fromv the condition ofthe wax, thereon.`

To these ends, my inver'itioir,therefore` consists of the novel manner 10i overlapping andv joiningsthe side wings, thebottom member,

and thetopfiap, sothat atleast a portion! of thesameis exposedat one central pointzon` the rear of the envelope and whensealing 1n waxis appliedto this particular point, it willbe impossible to remove the contents 4of 40 theenvelope .bysteaming land withdrawing any v015 the parts comprising the back of 'the envelope withoutx racturi-rig the .seal or tearing vthe part of fthe envelope withdrawn. In such oase, theltampering will be apparent,Y as theenvelope Aand seal cannot be glued' to its yoriginal condition, as would 'bethe case With anenvelopeofthe presentday`Y construction, whereone seal was used. It l will ftherefore be.apparent,that..by the use' of'this`-envelope-, thetinies'pent inl placingjo three seals' of vwaxfiipon` the envelopewifll be greatly4 diminis`hed,fl`4 the cost `of f sealing wax,` necessary orA sealingeach envelope; willi be considerably diminished,V an'dithe-i weight'of the" envelope will Ibe decreased: S0455 thatthe'cost'of its transmittal throughthe'f f 4rnailusljwill be lessthanvvith any envelopeA currency, andthel like. Before the Post havingl three` or more 'seaisY upon'the-same, all'ofiwhic'hfl saving has met with great favor in the trade 'and has proven 'the=invention'- to be a greatcommercial 'successr j l The advantagesand' objects which have been set VJ'rthabove will v be 'more apparent when-reference ishad to the followingder`Vr nection withthe accompanying drawing5fi-n f65 which:

K Like v"synrbols of 'referencerherein indicate! like parts in'A each ofthe figures-o'theidraJ-w# ks indicated in the' drawing, and particu larly in`v Fig.Y l, my', improved envelope is formed Vvfroml ya :single blank of 'any :desiredI material, such as paper, 'ib'roid, flexible'iber paper etc., andy these blanks Vare 'cut-J to thek shape shownwith a suitable'dief Thebl'ank: has ka central bodyportion'l 6 and side Wings 7"and 8on the respective sidesthereo' af bottoni member 9 with'ia recess 11iv therein; and atop or `closing'flap"12. In they first'v operat`fon of Aforming the envelopeytheside wing 7 is bentoverzonto thel body `portion 6 on the line 13, and the side wing 8 is bent over onto the said body portion on the line 14, and the outer end of the side winfr 8 falls beyond the outer edge of the side wing 7, so as to form the overlappingV joint .16, and this overlapping joint is provided with adhesive material 17 for securing side w1ngs 7 and 8 together. This operation is called tubing.

In'order to form the bottom of the pocket of the envelope and to make the corners thereof secure, so that nothing can be removed from the envelope, the bottom member 9, together with a portion of the body 6 and portions of the side wings 7 and 8, all of which are included and characterizedby the numeral 19, are bent upward on the line 21 Aover the remaining portions of the side wing 7 and 8, and the adhesive material 22 on the said bottomlmember, anda portion of the side wings 7 and8 isV dampened,rso'that.

said parts are secured tothe remaining'portions of the side wings, as shown in'Fig. 3. It will thus be seen that after the envelope has been so far constructed, all the ends have been brought to a'central position within and around the recess 1l in the bottom inember '9, and when valuables, in the form of stock, bonds, currency, or like matter, is placed in the pocket of the envelope, the

closing flap 12, together with the upper por` tions of the side wings 7 and 8, is bent on the folded line 23 onto the remaining portion of said side Wings, and moisture is applied to the adhesive material 24, so as to secure the said portions in position, and when so secured, the upper edge 26 of the closing flap will fall across the overlapping portions 16, so asto include both the side wings 7 and 8,

and will fall across the recess 11 of the -bottom Hap 9 so that when a single application of sealing wax 27 is applied at this point, the twoside wings 7`and 8, the bottom member 9, and the closing flap 12, will be connected to the said applied sealing member 27, and thus the envelope will be insured against opening, without breaking or distorting the said sealing wax.

It will be readily observed that while I have shown and described the recess 1l as being in the bottom flap 9 it may to all intents and purposes be in the closing flap 12 where it will give exactly the same results. For instance, if the flaps in the drawing were reversed Vand the closing flap called the bottom flap and secured in the same manner and the bottom flap-called the closing flap, the result obtained will` be exactly the same. Hence, I do not limit myself to any exact construction so long as the two side wings, bottom flap and closing flap are susceptible of having one application of sealing wax placed thereon for securing all parts together. Thus, while I have shown the recess as extending inward from the edge of the flap it will readily be seen that an opening in the body of the flap so as to include therein the edges of the two side wings and the other flap will be equally effective. Y

`Various modifications and changes in this invention will undoubtedly suggest themselves to anyone skilled in the art, and consequently I do not limit myself to theexact shape of the blank and its component parts as shown and described in the foregoing specification, but embody in my invention all such variations and modifications which properly fall within the language and spirit of the appended claims.

I claim:

1. An envelope comprising a body portion, imperforate side wing portions folded over said body portion, the outer ends of the'wing Y portions extending substantially together, i

and bottom and top flap portions Vfolded over said body portion, said wing portions and one over the other, one of said flap portions f having arecessed margin exposingthe margin of the other flap and a portion of the sur? face of each of said Wing` portions adjacent margins thereof, whereby a single wax seal may secure the wing and flap portions toouter free ends adjacent and overlapping one another, and bottom and top flap portions folded over said wing portions and one over the other, one of said flap portions having an opening exposing` part of the surface adjacent the marginal edge of each win portion and the other flap portion when sai portions.

are folded into position.

3.1An envelope having a central body portion, side wings folded over said body portion and having their ends overlappin and secured together, a bottomgfiap folde upward over said side wings and having its outer marginal edge secured thereto,a clos` ing flap extending downward over said side wings and being adapted to be secured thereto, and portions of each ofsaid wings, said bottomflap, and said closing flap being ex-` posed at substantialy a single` common place so that a single application `of sealing wax will contact with and secure allof said members together. A

Ll. An envelope comprising a central body portion, side wings adapted to be folded over said body portion and having their outer edges overlappingand secured together, a bottom flap adapted to be bent `upward together with a portion of Said central body andportions of said side wings, a closing flap adapted to be bent downward together with a portion of said central body and portions of said side wings, one of said flaps `having a recess atwhich place portions of t-he edgesv folded so that a single application of sealing Wax will Contact with and secure all of the same together.

5. An envelope having a body portion, 5 side Wings, aI bottom flap, and a closing flap, one of said flaps having an aperture, said parts being so folded that a portion adjacent the edge of each of said Wings and one of said aps meet at substantially a common f point within said aperture whereby asin le 10 application of Sealing wax will Contact with and secure said partsincluding said apertured' flap together.

In Witness of the foregoing I affix my signature.
